In regards to some of the claims that LPDMI is making in terms of hunter retention, linking it to APR's, some further analysis is worthwhile.
In the video on their website, hunter retention rates in DMU 122 are compared to those in 3 other UP DMU's, DMU's 152, 155 & 252. Those three DMU's had previously had the same APR's as DMU 122 but they were not renewed after 5 years, while the ones in DMU 122 were. The comparison then shows further changes in hunter numbers that have occurred since APR's were dropped in those 3 DMU's and continued in 122. Clearly, the implication is that the removal of APR's in those 3 counties caused hunter numbers to tank and that the continuation of APR's in DMU 122 is responsible for an increase in hunter numbers there. The primary problem with this is that during the period that Bio has lumped together in the 3 DMU's post APR's, there were two different sets of regulations in effect. In addition, it ignores what happend in regards to hunter numbers in those DMU's, during the 5 years that APR's were in place.
In order to make a reasonable assessment of any potential impact that APR's may have, you have to examine and differentiate between the different regulations that were in place during all of the periods that we have data for.
One way to do that is to look at what the average annual increase/decrease in hunters was in each DMU and contrast them on the basis of the regulations that were in place during those time periods. That will give us a sense of whether there is a clear and obvious impact resulting from specific regulations or whether changes in hunter numbers may be due to some other factors.
This chart compares 5 UP DMU's during three periods between 2001 and 2011. The regulations in effect in each DMU are color-coded. Red = 3 pt. APR, Purple = no APR and Blue = HC APR's.
In looking at these numbers, a few things stand out. During the 1st time period, 4 of the 5 DMU's had APR's but clearly something other then just APR's was spurring increased numbers of hunters in DMU 122 or else something else was causing hunter numbers in the other 3 APR dmu's to show substantially lower rates of growth. Comparing the non-APR DMU to 3 of the 4 APR DMU's does not show a very significant difference that could be attributed to APR's.
During the second time period, 3 of the 4 non-APR DMU's showed comparable levels of retention, as did the APR DMU and one non-APR DMU took a big hit in hunter numbers. Hard to point to the presence or absence of APR's as being the causative factors for any of those numbers.
The third time period compares 4 DMU's under HC APR's to DMU 122 which had a 3 pt. APR. 3 of the HC DMU's showed modest hunter loss, 1 was static and DMU 122 showed modest gains. In looking at those figures in a vacuum, one might attribute the modest gain in DMU 122 to the fact that it had APR's or you might conclude that HC APR's cause some hunter loss. But given the fact that DMU 122 showed substantially higher gains during the time period when 3 of the other DMU's also had APR's, it would be easy to conclude that some other factor is driving hunter retention/increases in DMU 122 that has nothing at all to do with APR regulations.
I'll give Bio credit for a slick video presentation but the implied conclusion that is being drawn from the data he provides is, in my opinion, a bogus one. Again, it's a shame that LPDMI has to try and fabricate reasons for people to support what they are selling.
